Cornea swelling:
Contact lens overwear, keeping eyes open too long in a pool, or other causes of swelling of the front of the eye can cause these symptoms. If pain and light sensitivity are also present, then an urgent visit to your eye doctor is needed!

Difficult to answer:
The most common cause for foggy vision in bright sunlight is a cataract; this is a clouding of the lens of the eye that happens with age. This is very treatable with glasses or surgery. Please see your eye surgeon for an evaluation and good luck!

Dry eye cataracts:
Anything which compromises the visual system of the eye may induce fog and glare. Most commonly, the culprits are dry eyes and cataract formation (haziness of the lens).

Migraines:
Migraine auras can be associated with flashing lights, and both vitreous and retinal detachments can be associated with light flashes. Even rubbing your eyes can cause transient light flashes. But repetitive spontaneous flashes need evaluation.

Laser :
Laser treatments to the eye may cause the vitreous jelly in the eye to move. The movement of the vitreous jelly may pull on the retina to cause flashing lights.
If the flashing lights increase in frequency or intensity, and if you see new floaters, you should return to your ophthalmologist for an examination.

Retinal changes, etc:
Sparkles termed photopsias, can occur from changes in the character of the vitreous in the back of the eye mostly due to aging, but can also be due to retinal detachments, and some inherited retinal changes. They can also be a thing that occurs with migraines. You should visit your ophthalmologist if you have these symptoms.

Floaters:
It depends on what condition you have. Most of the time this occurs as you age. The vitrous in your eye shrinks and can sometimes detach from the retina. If the back part of the vitrous falls into your line of sight you may see spots or even spider webs

Depends:
I'm assuming you mean halos around objects in your vision, like lights. Halos occur when any of the light rays entering your eye get scattered on their path to the retina (the seeing part of the eye). This could occur with dirty/scratched/outdated rx glasses, corneal irregularities (e.g., dry eye, allergies), cataract, floaters, and some macular disorders. An eye md (ophthalmologist) can help.

Probably not:
The most common symptom of vitreous change with age is the production of multiple floaters generally settling down to a few. Night glare and light scattering is a more common symptom of cataract and corneal changes, and also uncorrected need for eyeglasses. See your ophthalmologist if you have any of these symptoms to get the best diagnosis.

Several things...:
Your symptoms can be produce by different things such as early cataracts, ophthalmic migraines, uncontrolled blood pressure etc.. You need to be examined by an ophthalmologist to rule out some of these things.

Need a diagnosis:
Cloudy vision and halos can generally be caused by anything that interferes with light entering the eye, including hazy glasses or contact lenses. However, cataract is a common cause of this, and a less common cause is a scar of the cornea. Corneal swelling (edema) typically causes a rainbow type of halo, and this can be more serious, as it can occur with greatly elevated eye pressure.

Vitreous floaters?:
I suspect you are describing vitreous floaters - small bits of debris in the gel that fills the back of the eye. These are common, and are often described as looking like a gnat or hair that moves when your eye moves; more prominent looking at a blank background like the sky. New floaters, esp if ass'd w/ decreased vision and/or light flashes should prompt evaluation for a retina tear.

Vitreous detachment:
It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery.
